  <p class="para rdfs-comment">
   <span class="function"><strong>PharFileInfo::chmod()</strong></span> allows setting of the executable
   file permissions bit, as well as read-only bits.  Writeable bits are
   ignored, and set at runtime based on the
   <a href="phar.configuration.html#ini.phar.readonly" class="link">phar.readonly</a> INI variable.
   As with all functionality that modifies the contents of
   a phar, the <a href="phar.configuration.html#ini.phar.readonly" class="link">phar.readonly</a> INI variable
   must be off in order to succeed if the file is within a <span class="classname"><a href="class.phar.html" class="classname">Phar</a></span>
   archive.  Files within <span class="classname"><a href="class.phardata.html" class="classname">PharData</a></span> archives do not have
   this restriction.
